In one instance, Angie Atkinson purchased a case of Land O' Lakes Half & Half creamers and was disgusted when she opened them and found they were curdled.

"It didn't occur to me that you could even sell something that was expired," Atkinson said in an interview. "If I had bought it the first time and it was like that, I never would have bought it at all."

Amazon told CNBC that they have taken corrective action to deal with sellers who are shipping expired food items and explained the incidents were isolated.

"We work hard to make sure customers receive high-quality products when they order from our store," an Amazon spokesperson said. "We have robust processes in place to ensure customers receive products with sufficient shelf life. If customers have concerns about items they've purchased, we encourage them to contact our Customer Service directly and work with us so we can investigate and take appropriate action."
